LIP STICK AND COSMETIC CONTAINER Filed Dec. 9, 1933 Patented Apr. 30,1935 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to lipstick containers of the type in'which thestick of cosmetic is supported in a carrier and is moved from theenclosing casing to expose the stick for use and then withdrawn into thecasing, and it is an object to provide an improved construction by whichthe carrier of the cosmetic stick can discharge its entire amount ofcontents.

Lip stick containers now on the market are usually sold with the stickof cosmetic contained therein, and as the containers of the better classare comparatively expensive to manufacture the total cost of thecosmetic and its container is unnecessarily high as the ordinarycontainers in practice have been found not adapted for use with morethan one stick of cosmetic, due to the fact that it is difficult toremove the less accessible portion of the cosmetic stick. This featureis very objectionable as it prevents the use of a plurality of sticks ofcosmetic in one container and thereby increases the cost of the cosmeticto the users.

It is one of the objects of this invention to overcome the beforementioned objectionable feature and provide a cosmetic container whichmay be conveniently and easily recharged any number of times without thenecessity of removing the less accessible portion of the contents of thecontainer.

A further object of this invention is to provide a cosmetic containerwhich will discharge for use its entire amount of contents without thegenerally unsatisfactory results and the expense of time, labor andinconvenience incident to removing the less accessible portion of thecontents of the cosmetic carrier.

With the foregoing and other objects in view, this invention consists incertain novel features of construction, combinations and arrangements ofparts as will be more fully disclosed in connection with theaccompanying drawing.

Figure 6 is a partial side elevation and partial section of the innercasing #4.

Figure 7 is a side elevation of the sleeve #3 with spiral slot #6.

Figure 8 is a plan of the carrier sleeve with guide pin applied. Figure8 is on a slightly enlarged scale.

Figure 9 is a side elevation of the sleeve with guide pin applied.Figure 9 is on a slightly enlarged scale.

Figure 10 is a plan of the inner carrier sleeve to fit in carrier sleeve#8, Figure 8. Figure 10 is on a slightly enlarged scale.

Figure 11 is a side elevation of the inner carrier sleeve showing slots#12 and. #I3 used both as guide over pin #1 and to give spring tobottom. Figure 11 is on a slightly enlarged scale.

Figure 12 is partial side elevation and partial a opposite ends with itsupper end turned inwardly as shown at M to facilitate inserting it inthe lower open end of the cap I.

The propeller mechanism within the casing for moving the cosmetic tooperative position or retracting it into the casing comprises anintermediate sleeve 3 which is a strip of sheet metal having biased sideedges sothat when the strip is rolled into tubular form as shown inFigure 7 these edges form a spiral groove 6 extending throughout thelength of the sleeve.

The sleeve 3 embraces an inner rotary sleeve 4 which is of tubularconstruction closed at its The sleeve 3 is containedin the outer casingsleeve 2 in which it engages so closely frictionally as to move withsame.

The sleeve 4 has a longitudinal slot 5 which cooperates with the spiralslot 6 and a guide pin I to shift the cosmetic carrier longitudinally inthe casing. The carrier has an outwardly extending guide pin 1 from itsside wall projecting into the slots 5- and 6 of sleeves 4 and 3, so thatby relative rotation between these two sleeves this guide pin movesalong the two slots by the camming action created and slides the carrier(Figure 14), longitudinally to. either project the lip stick from theopen end of the sleeve for use, or to retract it into the sleeve asshown in Figures 1 and 5.

The cosmetic carrier consists of two pieces, a ring of tubing 8 open ateach end holding a guide pin 1 near its bottom edge and an inner sleeve9 somewhat longer than sleeve 8 and closed at one end, inner sleeve 9being made to fit inside sleeve 8, sleeve 9 being slotted in four placesboth to allow sleeve 9 to slide over guide pin 1 in ring 8 and to allowlegs of sleeve 9 to expand in sleeve 8.

When the lip stick contained in the carrier (Figure 14) is exhausted byuse to a point level with or below the top of sleeve 8, that portion oflip stick remaining in sleeve 8 may be projected upwardly from sleeve 8by degrees by rotating the sleeves 3 and 4, in a reverse direction, soas to retract the carrier into the sleeve 4; when the carrier has beenretracted to the point where it would normally come to a stop, due to-the legs of inner carrier sleeve 9 coming into contact with the bottomH of sleeve 4 it is merely necessary to apply a little extra effort inrotating sleeves 4 and 3 in a reverse direction; this will overcome thefriction between sleeves 8 and 9 of the lip stick carrier (Figure 14),gradually forcing sleeve 8 of the carrier downwardly, leaving exposedfor use that portion of lip stick contained in carrier sleeve 8. It willbe noted that only a fraction of a turn should be employed at a time, sothat only a small portion of remaining lip stick shall be protruded,otherwise the carrier telescopes within itself entirely and ceases to bea carrier, the top of inner sleeve 9 attaining a point level with thetop of outer sleeve 8. When the lip stick has been entirely exhaustedthe carrier (8 and 9) may be projected longitudinally to the end ofsleeve H, and the carrier bottom 9 may be pushed downwardly withincarrier sleeve 8 so as to form an empty carrier again, into which afresh lip stick may be inserted, retracted and projected the same as ifthe container were new, obviating the necessity for purchasing anothercontainer.

While it is believed that from the foregoing description, the nature andadvantages of the invention will be readily apparent, I desire to haveit understood that I do not limit myself to what is herein shown anddescribed, and that such changes may be resorted to when desired as fallwithin the scope of what is claimed.

Having thus set forth the nature of my invention, what I claim is: I

In a cosmetic container a hollow cosmetic carrier assembly slidablelongitudinally and open at one end to receive a stick of cosmetic, thecarrier assembly comprising an outer sleeve open at each end and havinga guide pin inserted near the bottom of same; and an inner sleeve closedat one end to form a movable and adjustable bottom for said outersleeve, said inner sleeve being slotted longitudinally from the open endto a point near the closed end to form four legs which spring outwardlypressing against the inner surface of the outer sleeve thereby holdingthe inner sleeve in a firm position relative to the outer sleeve; saidguide pin inserted at the bottom of said outer sleeve forming a base forthe top of said inner sleeve which rests in a straddle position oversaid pin.
